GAUGE.

Application filed September 1, 1920. Serial No. 407,561..

Yo Il nutons it may con-cern Be it known that lj Fna-nir Ermes, a citizen of the United States of America, and resident of Fort llVayne, in the county of tillen and State of lndiana, have invented certain new and useful improvements in Gauges, of which the following is a specifica.- tion.

rl`his invention relates to improvements in gauges adapted for use in connection with the visible type in which a glass measure is employed for displaying gasolene as it is dispensed. rllhe object of the invent-ion is to construct the gauge and apply it to a glass measure in such manner as to accurately indicate the level of liquid in the measure at various stages corresponding with-definite unit quantities of liquid held therein. Another object is to so construct the device that its indicating members may be adjustably positioned and subsequently secured from tampering by unauthorized persons.

The objects of the invention are accomplished by the construction illustrated in the accompanying drawings in which:

Fig. 1 is a front elevation of a glass measure showing the invention in connection therewith, there being parts shown broken away and in section;

Fig. 2 is a detail view showing a transverse section of the device on the line x-x of Fig. 1 and including the adjacent portion of the glass measure; and

Fig. 3 is a detail view showing a portion of the device in vertical section and including the adjacent portion of the measure to lwhich it is secured.

The invention is applicable to measures having a glass cylinder 1 into which liquid is run preliminary to being dispensed. rlhe measure herein shown as an example includes the glass cylinder mounted upon a bowl 2 having avalve controlled outlet port 8 near the bottom of the cylinder and an overflow pipe Al, the upper end of which is near the top of the Cylinder.r and also a cover 5 is positioned upon the cylinder to close its upper end.

rlhe invention is comprised of a series of indicating members 6, each of which consists of an elongated thin plate horizontally disposed and adjustably secured to a stationary supporting bar 7, the members being secured to the bar by any suitable means such as liquid dispensing apparatus, especially ofv screws 6. rllhe supporting bar 7 is vertically positioned in fixed relation with the measure so that the projecting ends of the indicating members are held against the wall of the glass cylinder.

The supporting bar 7 has two outwardly progecting studs 9, and a shield is positioned so as to cover the front of the supporting bar and the screws 8 which secure the indicating` members in position, the studs 9 extending through the shield and being perforated to admit of applica-tion of a seal 11 to prevent unauthorized removal of the shield and exposure of the screws 8. The uppermost indicating member 6 and also the lowermost indicating member 6 function in a similar manner to the members 6 and maypbe the samein construction if desired. *tach indicating member 6 has at each end a large sight opening 12 and a horizontal narrow slot13 that extends inwardly from each opening in line with the axis thereof. The upper most indicating member 6 presents a downwardly extending sight.

recess la at each end thereof and a horizontal upper edge 15 that extends inwardly from each recess. The lowermost indicating member 6 presents at each end thereof an upwardly extending sight recess 16 and a lower horizontal edge 17 that extends inwardly from each recess. y

ln the operation, when the measure is filled with liquid to its overflow level, the surface line thereof extends even with the upper edge 15 of the indicating member 6 and across the recesses lll therein. As the liquid is withdrawn from the measure the. surface line of the liquid recedes and may be observed through the sight openings of the indicating members 6 as it reaches the corresponding stages. It is the intention to position the various indicating members 6 so that the surface line of liquid in the measure vill show across the sight openings in line with the slots of the respective members at corresponding stages7 each stage being determined by definite quantity units of liquid in the measure. Then the measure has been emptied through its outlet port the surface line of the liquid remaining in the measure shows even with the lower edge 17 of the indicating member 6 and extends in line with the lower edge across the sight recesses 16.

The upper edge of the indicating member 6', the lower edge of the indicating member 6, and the horizontal narrow slots in the indicating membersv 6 are located respectively at such levels as are attained in the measure by the suriace oi the liquid when the content oft liquid is ot the quantity corresponding with the amount the respective members are designated to indicate.

Upon the shield l() are displayed a series of indicating characters 18 corresponding in position with the respective indicating members and being significant in each instance oi the particular number of units oi' measurement indicated thereby. ln the event the surface line ot the liquid, when at rest, -tails to register' even with the horizontal slots or indicating edges of the n'iembers, Vsuch variation becomes plainly apparent by observing the surface line eX- tending across the sight openings out of line with the horizontal indica-ting slots or edges ot the members.

With the gauge members, thus constructed, the various unit quantities of liquid may be very accurately designated and easily observed as the surface Aline recedes during the withdrawal of the liquid from the measure.

rl`he horizontal slots in the indicating members may be of extreme narrowness and still be plainly visible because of the light emitted therethrough, and the sight openings tend to concentrate the vision of the observer focally to the slots. Thus, the operator is aided in bringing` the surface level of liquid accurately tothe levels indicated respectively by the horizontal slots.

What I claim is:

l. In a gauge for transparent liquid measures, an elongated indicating member having a sight opening in each end thereof and a comparatively narrow level-indicating slot extending from each sight opening; and means for supporting the member in horizontal position.

2. In a gauge for liquid a transparent measure, a. series of indicating members, each having a narrow Vlevel-indicating slot and an adjoining sight opening through which the surface line oit liquid in the measure may be observed when in proximity to the slot; and means for supporting the inember in operable relation with the measure so that the slots therein are held parallel with the level. of liquid in the measure.

3. ln a gauge for liquid a transparent measure; and a series of members mounted in juxtaposition with the measure, each having a sight opening and a comparatively narrow level indicating slot in line with the axis of the sight opening.

4. ln a gauge for liquid, a transparent measure a series of membersin supported relation with the measure, each having a level-indicating means and corresponding sight openings extending therethrough and Yarranged in line with said means.

5. in a gauge for liquid, a transparent measure; a vertical supporting bar attached to the measure, a series of indicating members adjustably secured to the bar, each member having a level indicating means and sight openings in line therewith; and a shield secured in connection with the supporting bar, 'adapted to preventJ ltampering with said members.

6. n a gauge 'for liquid, vva transparent measure; a'supportin'g means attached to the measure; a series ot indicating members including means toradjustably securing the same to the supporting'means; vand a shield 'removably sealed in connection with the supporting means and covering the securing means.

.lin testimony whereof lf affix my signature, in presence of two witnesses.
